Abstract
In order to expand the application range of surfactants, two chiral surfactants named CTACYT and CTATYS were synthesized by reacting cetyltrimethylammonium chloride (CTAC) with L-cysteine and L-tyrosine, respectively by a simple method. Studies show that the foaming ability, foam stability and emulsifying properties of both CTACYT and CTATYS are superior to CTAC. The corrosion inhibition efficiencies of CTACYT and CTATYS are 96.72% and 90.22%, respectively, which are higher than that of CTAC. The new chiral surfactants remain the chiral character, and the specific optical rotations of CTACYT and CTATYS were 8.1° and 11.6°, respectively. This work provides a new and easy way to the synthesis of chiral surfactants, which will benefit the related research in this field.
